The testing has been carried out by people with sufficient technical competency to carry out the tests.
1. Operating Range: Two tests should be carried with the Power Generating Module operating at Registered Capacity
and connected to a suitable test supply or grid simulation set. The power supplied by the primary source shall be kept
stable within ± 5 % of the apparent power value set for the entire duration of each test sequence.
Frequency, voltage and Active Powermeasurements at the output terminals of the Power Generating Module shall
be recorded every second. The tests will verify that the Power Generating Module can operate within the required
ranges for the specified period of time.
The Interface Protection shall be disabled during the tests.
In case of a PV Power Park Module the PV primary source may be replaced by a DC source.
In case of a full converter Power Park Module (eg wind) the primary source and the prime mover Inverter/rectifier
may be replaced by a DC source.

2. Power Quality – Harmonics:
For Power Generating Modules of Registered Capacity of less than 75 A per phase (ie 50 kW) the test
requirements are specified in Annex A.7.1.5. These tests should be carried out as specified in BS EN
61000-3-12 The results need to comply with the limits of Table 2 of BS EN 61000-3-12 for single
phase equipment and Table 3 of BS EN 610000-3-12 for three phase equipment.
Power Generating Modules with emissions close to the limits laid down in BS EN 61000-3-12 may
require the installation of a transformer between 2 and 4 times the rating of the Power Generating
Module in order to accept the connection to a Distribution Network.
For Power Generating Modules of Registered Capacity of greater than 75 A per phase (ie 50 kW) the
installation must be designed in accordance with EREC G5.

3. Power Quality – Voltage fluctuations and Flicker:
For Power Generating Modules of Registered Capacity of less than 75 A per phase (ie 50 kW) these
tests should be undertaken in accordance with Annex A.7.1.4.3. Results should be normalised to a
standard source impedance, or if this results in figures above the limits set in BS EN 61000-3-11 to a
suitable Maximum Impedance.
For Power Generating Modules of Registered Capacity of greater than 75 A per phase (ie 50 kW) the
installation must be designed in accordance with EREC P28.

Applies to three phase and split single phase Micro-generators.
^ Applies to single phase Micro-generators and Micro-generators using two phases on a three phase system.
For voltage change and flicker measurements the following formula is to be used to convert the measured values to
the normalised values where the power factor of the generation output is 0.98 or above.
Normalised value = Measured value × reference source resistance/measured source resistance at test point ×
3.68/rating per phase.
Single phase units reference source resistance is 0.4 Ω
Two phase units in a three phase system reference source resistance is 0.4 Ω.
Two phase units in a split phase system reference source resistance is 0.24 Ω.
Three phase units reference source resistance is 0.24 Ω.
Where the power factor of the output is under 0.98 then the X to R ratio of the test impedance should be close to that
of the Standard Impedance.
The stopping test should be a trip from full load operation.
The duration of these tests need to conform to the particular requirements set out in the testing notes for the
technology under test. Dates and location of the test need to be noted below.

a larger deviation than the minimum required to operate the projection can be used. The “No trip tests” need to be
carried out at the setting ± 0.2 Hz and for the relevant times as shown in the table above to ensure that the protection
will not trip in error.
